For what it's worth...
My Uno's (2.0) are on Audioplan Antispikes and I plan to alter things like this: subwoofers on sorbothane blobs (I have a wooden floor, placed on a concreet base with felt in inbetween). This will stop the transfer of vibration into the floor. Under the supports for the tweeter/midrange, you van put spikes and such as they are blessed with threaded holes. By loosening the screws between the supports for the tweeter/midrange and the subwoofer, there will be some de-coupling.
Added bonus in my view is the fact that it makes leveling of the tweeter/midrange easier as there will be three points to adjust iso four. Placing the speaker exactly upright with precise tilt is extremely important in my view.
Last but not least: someone once told me that the subwoofers themselves are not that well damped. Looking inside you see that there is one sheet of damping foam present. This person had done some experimenting and suggested to put the damping foam in the back of the enclosure and to fill the enclosure with "Angel hair". This will lower the Qts and will lower the resonance frequency somewhat.
